PADiKA l I Application mea June 6,' isaj s'eiarNo siamo. 'd i This invention relates generally to locks,

more specifically to that form of locks com- Y Inonly known as padlocks.

The principal object of the present invention is to provide a lock in which the shackle is removably secured to the body by screw threaded connections in lieu of the usual f locking mechanisms. y Another object is to provide a locking device of strong and durable construction which is particularly adapted for use in locking electric meter boxes, gas valves or the like to cut oif the service therethrough and which are to `remain vlocked Vuntil the service is again restored.

VOther objectsV and advantages will be apparent from the following description, reference being had to the accompanying drawing, in which:

Fig. 2 is a horizontal section taken -sub-` stantially on line 2-2 of Fig. 1.

Fig. 3 is a section taken through the body of the lock.

Fig. 4 is a side elevation of the from the body. A

Fig. 7 is a perspective view of the device shown in Fig. 6 with the bow in open or unlocked position. Y l Y l Fig. 8 is a side elevation of the locking plug of the device.

Fig. 9 is a plan view of the plug. A Fig. 10 is a perspective view of the wrench or key-employed to manipulate the plug.

Referring more specifically to the drawing, 10 generally designates the improved locking device whichconsists of a body 12, a shackle 14, and a screw threaded plug 16, the latter p serving to hold the shackle in locked engagement with the body.

Body 12 is preferably of cylindrical shape, having a screw threaded bore 18 therein, and formed in its upper portion are oppositely 'disposed recesses which communicate with clearly shown' in'F ig. 1.

The shackle is held in permanent engage- ,ment with the body, i. e.v so thatit cannot become accidentally lost, by a collar or abut-y ment 49 formed on the lower end of arm 48.

When in locked position as shown the Y threads on plug 44 engage threads 47 of the shackle as shown in Fig. 5. v

By unsorewing the plug to a position below threads 47 with the wrench, as shown in Fig.

ll0, the device may be unlocked. 1When thus released theshackle may be raised and swung to one side as shown in Fig. 7

locking device may be employed in the same manner as the usual padlock, is of simple con-y struction and may be veasily and 'cheaply produced.
